docs rewrite

[threepointone]

goals for the rewrite are -

• explain the why (the 'css as values' spiel)
• explain the how, geared for beginners
• deep dive into advanced usecases
• how it's better than CSS (and it is!)
• start work on something nicer looking than an .md file (github-pages, maybe?
• cleanup of /docs folder

I volunteer to help build this with Gatsby + Glamor! I'll be building several documentation sites soon so the more the merrier :-)

Hey,

I started to work on a condensed version of the documentation. It's a .md file so I don't know if you are interested. You can find the doc here

It could be a good starting point while waiting for the GitHub page or the Gatsby doc.
